Steel Steam and Flame

Cassia found an entrance and exit, the muscles in the throat squirmed, and a voice with strong penetrating power was stimulated, and layers of ripples appeared in the air, spreading out for tens of meters before stopping. And the whole body of Cassia, especially the fan-shaped area in front, the rotten and dead leaves of Shi Lan silently cracked, becoming boiling and beating fragments on the ground.

The sound cannot be heard by the ears, it carries a heavy force and is transmitted along the network through the underground passage. Cassia continued to make sounds with a predetermined pattern to maintain the existence of the source, which enabled Cassia to locate and come here faster. The tunnel network has expanded too wide. If it wasn't for the breath of dragons to control and intimidate other second-class creatures, this network of underground passages would definitely be a place where a large number of creatures converge.

After two or three minutes, Cassia leaned close to the ground to get feedback on vibration and sound. More than ten minutes later, with a rumbling sound, a huge slate was pushed open, and the fallen leaves flew in the sky in one space. On the hideous head covered with black scales.

No matter how he breathed, or slightly opened his mouth to make a sound of "ah, oh,,,", the high temperature and hot air spurted out, and blew away the fallen leaves. In just a few seconds, the dead leaves had been emptied, revealing a large number of trees with bare roots and knots. The black wet land came.

Cassia drilled out of the exit, shaking her body from time to time, and a large amount of dry soil and fragments fell like hail, and Cassia had to step back a little to avoid it. I didn't bring that great sword, but several years had passed, and the growth rate of dragons of the same age was far faster than the growth rate of dragons of the same age.

"Dagger?" It would be better to call it this way. After all, compared to Kashye's body length of over 140 meters at the moment, after a little while, perhaps the contact test of this pollution was successful and a large amount of food was obtained. It can reach a body length above 150 meters. At that time, Kathy Black will also officially go to the fourth stage and become a high-stage dragon.

"Ah,, Kar,, quack,, ah,, a little,,,," Cassia turned around, and even though the huge head was already on the ground, it was still much higher than Cassia. The sound of roaring made the air vibrate, and there was a faint sound of explosion. But fortunately, the dragon's field of vision is almost 360 degrees, and it can see Cassia standing in front of his head.

No matter the breath or the appearance, it is not the same as a few months ago, but it is the same as nearly three years ago. This is its simple judgment basis.

"I've grown up a lot!" Mental perception depicts Cassia's current body shape, Cassia sighed, and listened to what Cassie said in dragon language. Not a lot of content, said a lot, but it can be summed up in one thing—

There are many tunnels, the tunnels are very large, the tunnels are very long; the roots are many, the roots are large, the roots are very long,,,

At the same time, there are fears and questions in it. Cassie felt a very dangerous aura a long time ago, but it disappeared quickly. He also said that he went there again after that, but he didn't find Cassia, so he returned here and waited, and he would go there again from time to time. He also said that he had been digging here for a long, long time. …

Cassia could only sigh and answer in simpler language, saying that because of delays in many things, she could not return here in time. But in the time to come, I'll probably be able to see myself often...

Not long after, Cassia jumped on Cassie's head, and one person and one dragon got into the tunnel network, and quickly went under the ground with the sound of rumbling.

It was still the part of the visit that Cassia expected. The tunnel network was Kashye's interest, and perhaps it was the reason why he felt more or less safe in hiding underground when he was attacked by the surgeon. The voice is not only happy, but also excited. From its perspective and understanding, it shows that the tunnel network can go to many places, how long it takes to complete the longest one, and so on.

When the slate was covered, Cassia didn't expect that the channel network after going deep underground was no longer the dark version of a few years ago. The channel is obviously much larger than before, and the depth is also much deeper. At this moment, there is a faint fluorescent light, and the color of dan green towards dan blue comes from the fluorescent moss that appears on the inner wall of the channel from time to time.

It's a large area, not everywhere, but it's enough for the extremely strong low-light vision that both Cassia and Cassie have.

Cassia asked in simple words at this time, and Cassie stopped and looked at it before answering, I don't know how long it will take, these things will appear, and it doesn't know the specific time,,,

Faced with an answer that wasn't an answer, Cassia could only tacitly assume that Cassia went to a place with this kind of moss somewhere, and brought them back by scratching their claws or body scales.

"Maybe there is also the reason for the root system of ancient trees." There are bare tree roots and stems nearby where the fluorescent moss is located. Only these places can maintain a long-term wet environment. With Cassie's body temperature of 10 degrees at the moment, the temperature of the tunnel network is not very high, but it is warmer than the autumn temperature on the ground.

"But fortunately, it was not contaminated." At the same time, Cassia was also silently rejoicing in her heart. The first time he saw the tan-green-to-tan-blue fluorescence, he immediately thought of uranium-gold radiation. After I didn't feel the pollution of radiation, I relaxed my mind, and with Cassio as a guide, I started to visit the channel network at a good speed.

After walking through one passage after another, and after passing through dozens of huge underground cavities serving as transfer stations, Cassia not only saw a large number of spare materials accumulated by Cassie Black - one after another, polished and polished entrance and exit covers. , I also saw a lot of rock blocks that were used for throwing attacks, which were much larger than a few years ago,,,

There is a large pile, and it seems to be neatly placed, and there is a corresponding reserve in each underground cavity. There are also, but not limited to, sword-shaped weapons made of rock, both long and short, of various types, all of which are marked with strange characters with their claws. There are also weapons made of ancient tree trunks, dozens of meters in length, have become dry, and some have a lot of cracks.

Some of them have been used, and Cassia saw the gap after the slash. There are also ones that have never been used, probably like rock blocks, which are used by Cassie as a backup. But now, the weapons made of these ancient tree trunks have become supports for the underground cavity. What are the reasons for the attraction of the same kind to each other? A lot of knotted tree roots have climbed on it, and fluorescent moss has covered most of the area, giving it the feeling of a vertical lamp.

A tenacious and delicate life, Cassia sighed at this time.

After advancing in the tunnel for more than ten minutes, Cassia felt that after walking a long distance, Cassie suddenly roared, with a smell of wanting to share good things, but being afraid.

After listening carefully, Cassia answered with a general certainty, and smashed the scales under her body—a way of comforting the dragons by the surgeon, and the force was too light to be felt—so that Cassie didn’t have to worry.

"That piece of ancient historical world,,, wood fragment that you found when you dug a tunnel a few years ago?"
